The invention relates to a metrology device (200) which is used to monitor an upstream broadcast signal comprising one main component and upstream control data. The inventive metrology device (200) comprises: a recovery circuit (220) which is used to recover the upstream control data from the upstream broadcast signal and to supply an upstream instruction; and a measuring circuit (230) which is used to measure a parameter of the upstream broadcast signal in accordance with the upstream instruction and to supply a measurement result. According to the invention, the metrology device (200) also comprises: - a control circuit (250) which is used to produce a downstream instruction from the measurement result and from an upstream result which is produced by the recovery circuit (220) using the upstream control data; - an insertion circuit (240) which is used to produce a signal to be broadcast downstream comprising (i) the main component of the upstream broadcast signal and (ii) downstream control data comprising the downstream instruction.
L'invention concerne un dispositif de métrologie (200) pour la surveillance d'un signal diffusé amont comprenant une composante principale et des données de pilotage amont. Le dispositif de métrologie (200) comprend un circuit d'extraction (220), pour extraire les données de pilotage amont du signal diffusé amont et fournir une instruction amont, et un circuit de mesure (230) pour réaliser une mesure d'un paramètre du signal diffusé amont en fonction de instruction amont et fournir un résultat de mesure. Selon l'invention, le dispositif (200) de métrologie comprend également : - un circuit de commande (250), pour produire une instruction aval à partir du résultat de mesure et d'un résultat amont produit par le circuit d'extraction (220) à partir des données de pilotage amont, - un circuit d'insertion (240), pour produire un signal à diffuser aval comprenant d'une part la composante principale du signal diffusé amont et d'autre part des données de pilotage aval comprenant l'instruction aval.
